SPECIFICATION formingpart of Letters Patent No.631f dated August 22,1899.

Application filed April 28, 1898- To all whont it nwry concern.-

Be it known that I, ALBERT FAUCK, a citizen of the United States,residing at Marcinkowice, in the Province of Galicia and Empire ofAustria-Hungary, have invented new and useful Improvements in Rigs forBoring 'Wells, of which the following is a specifica-' tion.

My invention more especially relates to that method of boring wellsaccording to which an annular section of the rock is operated upon andcut away, so that a core is formed in the center of the hole. In orderto remove the said core, it was necessary hitherto from time to time towithdraw the rod and bit wherein the sections of the core were retained.It is obvious that this alternate withdrawing and lowering out of therod and bit consumed much time and labor.

The object of this invention is to overcome these difficulties and toprovide means for removing the core without withdrawing the rod and bit.

According to my invention the tubular bit and rod are very rapidlyreciprocat'ed in strokes of little throw, the tubing of the well istightly closed at top, and a stream of .water is forced down through thesaid tubing.

The water ascending through the tubular bit and rods carries along thesections of the core, which are prevented from clogging by thecontinuous shake of the bit and rods. I impart to the drill its rapidreciprocating IDO- tion by suspending it from a rope, the other end ofwhich is secured to the derrick and which is run around a pulleylooselymounted upon the crank-pin of a revolving crankshaft or upon aneccentric-shaft journaled in the derrick below the point where the endof the rope is fastened. The tubular bit has reaming-cutters pivoted toits lateral sides, and its radial cutting edges are at two diametricallyopposite portions of greaterlength than the rest, whereby jamming in ofthe drill is prevented.

In order to make my invention fully understood, I shall hereinafterfnlly describe the same with reference to the accompanying three sheetsof drawings, in which Figure 1 is a sectional elevation on line 1 '1,Fig. 2, of my improved boring-rig; Fig. 2,

a sectional elevation on line 2 2, Fig. 1; Fig.

Serial No. 678,683. W0 model.)

3, a sectional elevation, drawn to a larger scale, of the lowerextremity of the hole being bored, the bit, the reamers, the tubing,

and the core. Fig. 4 is a horizontal section on line 4 4, Fig. 3, andFig. 5 is an end View of the bit.

Referring to Figs. 1 and 2 of the drawings, a is the wooden derrick,built up in the wellknown manner of sleepers, a base-frame, standards,struts, and a top frame. The driving-shaft b, to which motion isimparted from any suitable motor by means of the rope-pulley b,transmits the motionjby means of the rope-pulleys Z7 and c andthe.drivingrope d to the crank-shaft c, which may be replaced by aneccentric-shaft. When it is required to revolve this latter morerapidly, the driving-rope d is passed around the pulleys b and c of theshafts b and 0, respectively, and the pulley b is geared with the motor.

The rope d, from which the drill is suspended, has its end fastened to adrumf, the shaft of which is journaled in bearings secured to struts ofthe derrick a. The said shaft of the drum f-also carries a worm-wheel f,in gear with the worm f to the shaftf of which is secured a hand-wheel fIt will be readily understood that by turning the hand-wheel f the roped, wound around the .drumf, may be lowered out or shortened in. From thedrum f the rope d runs over a guide-pulley I, the pivot of which restsupon the cross-beams a of the derrick, and from this pulley downwardover a pulley g, which is loosely mounted upon the crank-pin of thecrank-shaft 0. Then the rope is passed upward to be slung around aguide-pulley h, mounted upon the top frame of the derrick in such aposition as to bring the downwardly-extending portion of the rope d intothe axis of the well.

By means of a stirrup i the rope d is connected with the tubulardrill-rode, which en-- ters the tubingj of the well throughastufiing-boxj made integral with the cap j that is screwed upon the topsection of the tubing j in order to tightly close it. The said cap j isprovided with a branch j 3 to be coupled with a hose Z, through which astream'of water under pressure is forced into the tubing j. The streamof water flowing downwardin the tubing passes at the bottom of the wellinto the tubular bit 7t 70 k hereinafter more fully described, andcarrying along the loose sections of the core it rises within the bitand tubular rod i, the top end of which carries a vessel m, intended toreceive the sections of the core. The hose Z carries ott the water.

The tubular bitis composed of threepartsviz., the bit proper, 7a, thereamer-carrier 7t, and the connecting-piece 70 to be screwed into thetubular rod The bit proper, 7c, is provided with radial cutting edges 91and 12, formed on its face, the diametrically opposite edges n beinglonger than the edges n in order to prevent jamming of the bit in acertain measure, as thenumber of diametrically opposite portions subjectto jamming is thereby considerably reduced. The reamer-carrier 70 hasreaming-blades o pivoted in suitable recesses of its sides. The headedpins 0 bear against shoulders 0 of the naves of the blades 0, and underthe action of coiled springs o abutting against the screw-plugs o, bywhich the bores 0 containing the pins o, are closed, the said pins causethe blades 0 to swing outward. \Vhen the drill is withdrawn from thewell, they fold against the reamer-carrier 7; as soon as they meet thebottom edge of the tubing '0.

It will be readily understood that the pulley g, mounted 011 thecrank-pin of the 0011- I tinuously-revolving crank-shaft c and actingupon a bight of the rope d, from which the l drill is suspended, mustimpart to the latter When the rope a rapid to-and-fro motion.

d is run over the guide-pulley I, the portions 3 of the rope on eitherside of the pulley g are parallel, and consequently the throw of the 1drill must be double the throw of the crank. Q In order to affordpossibility for reducing the I throw of the drill, there are yet threeother guide-pulleys II, III, and IV, suitably mounted to the derrick insuch positions as admit of directions more or less deviating from the 3parallel one being given to the portion of rope between the drumfandpulley g. The different directions the rope may be given are indicatedby dotted lines in Fig. 1, and itis obvious that with the guide-pulleyIV the shortest throw will be obtained, and with the pulleys III and IIgradually longer throws. Having fully described myinvention, What Iclaim, and desire to secure by Letters Pat;- ent, isi In a well-boringrig, the combination with 1 a derrick, a revolving crank-shaft journaledin the same, a pulley loosely mounted to the crank-pin, a guide-pulleymounted upon the top of the derrick, and a rope running from a fixedpoint of the derrick above the crankshaft around the crank-pin pulleyand guidepulley of a tubular drill-rod, a tubular bit having on itscircular cutting-face radial cutting edges, which are outwardly extendedon two diametrically opposite portions of the said cutting-face,reaming-blades pivoted to I the bit, a tubing closed at its top andmeans for forcing water into the said tubing, substantially as and forthe purpose set forth.

In witness whereof I have signed this specification in presence of twowitnesses.

ALBERT FAUCK.
